What fish is known for moving on land using its pectoral fins? The answer is the mudskipper.

Mudskippers are amphibious gobies in the subfamily Oxudercinae. Their jointed pectoral fins work somewhat like short limbs, helping them crawl, skip across mud, and even climb low vegetation. Fused pelvic fins can act as suction devices, giving them extra grip on wet surfaces.

Their land-based lifestyle requires more than unusual locomotion. Mudskippers keep their gill chambers moist, absorb oxygen through the lining of the mouth and throat, and can exchange gases through their skin. These adaptations allow them to remain out of water, although they must stay damp and generally live in humid intertidal habitats.

The name describes a group rather than one species: about 25 living species are recognized. They are not walking with true legs, and their pectoral fins are not the same as the limb-like fins of some unrelated fish. Their ability to move over exposed mudflats evolved alongside specialized eyes, breathing structures, and burrowing behavior.
